After doing some research I looked into sealing the Aluminum with a high temp clear coat. I pick up a bottle of Dupli-Color High Temp Clear (DE1636), and tried it out on the back of my intake manifold. For starters, here is what it looked like after buffering.

 I took off the wax, and got ready for the clear.

After the clear coat.

After three hours of curing.

I will let it dry for the recommended 24 hours. It has some orange peel. I will sand and buff soon, but I will remove the wax after buffering. I am sure the heat from the intake and valve cover will melt the wax. I will post pics of the experiment when I am done. If this doesn't work, looks like I am going to try the Zoop Seal.

Update

Well I tried the high temp clear coat and it didn't work. The clear coat was to cloudy, even after sanding an buffering. Tried so much, I broke through the coat. I putting in an order fro Zoop Seal tonight. Thanks for the help. See pics below.
